Realistic · 16:9 · 2048×1152
The widget on this page is the real embeddable generator, set up for YouTube video thumbnails. Write a sentence, pick a style chip, press the button: the picture comes back at 16:9, 2048 × 1152 pixels, from the same model the main app uses. It runs on our own key, so you can try it here before you sign up for anything.
Putting the same box on your own site
Every choice you see here is made in the widget builder: which controls the visitor gets, which styles are offered, which prompt suggestions appear, the aspect ratio and the image size. The builder writes one script tag with those choices in its data attributes. You paste it into your page and add your own domain to the allowed list, so nobody else can spend your credits with the same key.
| Setting | Value on this page |
|---|---|
| Aspect ratio | 16:9 |
| Image size | 2048 × 1152 px |
| Styles offered | Realistic, Comic, Neon, 3D |
| Cost | 1 credit per image |
Prompts that work for YouTube video thumbnails
Name the subject, then the surroundings, then the light — in that order. A prompt like "a product on a table" leaves almost everything to the model; "a matte black bottle on a pale stone shelf, soft window light from the left" leaves far less, and what comes back is much closer to what you pictured. The style chip adds a fixed opening phrase to your sentence before it is sent, which is why the same words look different in Realistic and in 3D; the style list shows every one of them. If you are writing prompts for the first time, the prompt guide is the shortest way in, and pricing explains the one credit each image costs.
